Warsaw: Poland's defense minister says that there has been "unprecedented" activity by Russia's navy and air force in the Baltic Sea region in recent days.

Tomasz Siemoniak said today that the majority of the incidents involved Russian operations in international waters and airspace, and that Sweden was the country most affected.

Siemoniak said Poland does not see Russia's show of military strength as a preparation for war. Instead, he called it a Russian attempt to test NATO, adding "but it doesn't help to build good relations and trust."
